Okay, I'll admit that after 23 years on the type, I'm still learning, but is it just me, or is A37575's post deeply offensive to anyone else whose qualified ?
I've done sectors as short as 22 minutes, and as long as 6 hours, but I don't recall ever being as slack as this poster insinuates.
It seems, according to A37575, that any sort of formal investigation is not required, he/she has it all completely sussed. Clearly, it was badly handled by the flight crew on the day.
I flew this aircraft for six different operators .... FYI Sir, the flight crew of the airline in question, have a very high standard, to which a lot of other companies aspire.
If you have some " Inside knowledge " that you would like to share, then please go ahead. If you don't then IMHO, you should apologise on this thread.
